AI voice cloning already produces real financial harm: a 7,000-person, 11-country survey finds 1 in 4 people affected (India 50%), average losses above $11,000, and fraud volumes spike to 10.2 million attacks after ChatGPT. Attackers use scraped voicemail or social audio plus open models (Llama 2, Megabyte) to create real-time voice clones, replayed asynchronously to extort thousands; humans detect fakes only ~57% of the time while t-SNE shows synthetic audio tightly clustered. A prototype synthetic-fraud adapter alerts landline users in real time; deep-fake CAPTCHA research reports >90% accuracy for anti-clone challenges.
